SHUTTLE FOR AUTOMATIC LOOMS AND FILLING-CARRIER THEREFOR.

SPECIFICATION forming part of Letters Patent No. 772,505, dated October 18, 1904.

Application filed June 22, 1904. Serial No. 213,591. (No model.)

I citizen of the United States, and a resident of Hopedale, county of Worcester, State of Massachusetts, have invented an Improvement in Shuttles for Automatic Looms and Filling- Carriers Therefor, of'which the following description, in connection with the accompanying drawings, is a specification, like characters on the drawings representing like parts.

This invention relates to shuttles adapted to be used in automatic filling-replenishing looms of the Northorp type, shown in United States Patent No. 529,940,- and to filling-carries for use in connection with such shuttles. The shuttle used in such looms is provided with notched spring holding-jaws, located at one end of a longitudinal opening in the shuttlebody, and the head of the filling-carrier is provided with a series of annular projections or rings to enter the notches and be held by said jaws in operative'position in the shuttle. If the shuttle is too far in the shuttle-box at time of replenishment, the notches in the holding-jaws will not be in proper position to receive the rings on the head of the incoming filling-carrier, and the latter will not be securely held in the shuttle, resulting almost certainly in some injury to the warp or to the mechanism of the loom. Heretofore an in clined guide has been interposed between the inner ends of the jaws, and when the shuttle is too far in the box the head-of the fillingcarrier will engage the guide and cause relative longitudinal movement of the shuttle and filling-carrier to bring the notches of the jaws eration, so that any positioning movement must be made by the shuttle.

In my present invention I have provided the shuttle with an upright guide between the inper ends of the holding-jaws, and I havedeinto position to bring the notches in the jaws opposite the rings of the filling-carrier. The projection on the outer end of the head is adapted to be engaged on its upper surface by V a portion of the transferring instrumentality during transfer, so that any tendency of the tip of the filling-carrier to,be improperly depressed will be obviated. Sometimes'this depression of the tip when it occurs will snap and break the filling, and it appears to be caused by a tendency of the filling-carrier to rock between the transferrer and the holdingjaws at the instant it is being inserted in the shuttle. This rocking tendency may be increased when the outer end of the filling-carrierengages the guide between the holdingjaws; but byproviding a part of the transferrer toengage the top of the projecting outer end of the filling-carrier head such rocking tendency is prevented absolutely, and the tip of the filling-carrier is truly and accurately positioned. I

The novel features of my invention will be fully described in the subjoined specification,

and particularly pointed out in the following.

claims.

Figure 1 is a side elevation and partial longitudinal section on the line 1 1, Fig. 2, of a loom-shuttle with a filling-carrier about to be inserted therein embodying my present invention, a portion of the transferrer being shown in section. Fig. 2 is a top or plan view, on a larger scale, of the holding endof the shuttle shown in Fig. 1 with the filling-carrier positioned therein; and Fig. 3 is a side elevation of the end of the shuttle shown in Fig. 2 with the filling-carrier moved downward partway, the holding-jaws being improperly positioned to receive the rings on the head thereof.

The shuttle A, having an elongated opening A therethrough to receive the filling-carrier, the side delivery-eye a Fig. 1, the automatically self-threading device T, and the laterally-yielding or spring holding-jaws 0, having upright notches 0* in their inner faces, maybe and are of well-known construction in loom-shuttles of the type to which this invention pertains. The jaws are secured at their inner ends by a block 0', Fig. 1, which is fitted into a recess in the shuttle-body, as usual, and retained in place by a transverse bolt 0 In the present embodiment of my invention an upright guide 1, made as a metal plate, is interposed between the inner ends of the holding-jaws and held in place by bending its ends 2 3 over the top and bottom of the block 0 as clearly shown in Fig. 1, and preferably the upper end of the guide is curved rearwardly, as at 4, between the guide portion and its bent end 3. As best shownin Fig. l, the curved portion 1 is located above the upper edges of the jaws.

I have herein shown the filling-carrier as a cop-skewer and comprising a split or spring blade 5, a cylindrical metallic head 6, secured thereto, and a series of annular projections or rings 7, mounted on the head to enter the notches 0 in the jaws in a well-lrnown manner. The outer end of the head is extended beyond the rings and shaped to form a tapered or conical projection 8 for a purpose to be described, said projection being preferably made integral with the head.

Referring to Fig. 1, the filling-carrier is supposed to be about to be inserted in the shuttle, and it will be seen that the notchesin the jaws are in correct position to receive the rings 7, so that when fully inserted in the shuttle, as shown in Fig. 2, the head of the filling-carrier will be held securely in position within the shuttle by the jaws. Should the shuttle be too far out of the shuttle-box, however, the jaw-notches will not be properly positioned to receive the rings, and in Fig. 3 I have shown such a case, but somewhat exaggerated. When this malposition of the shuttle occurs, the tapered end 8 of the filling-carrier head will in its descent engage the top at of the upright guide 1, and as the filling-carrier is pushed downward the guide will slide along the inclined face of the projection 8, causing the shuttle'to move to the left, viewing Fig. 3, and thereby bringing the notches of the jaws into proper receiving position for the rings 7. By rounding the top of the guide, as at 4, wear on the cooperating guide and projection is reduced, and the sliding movement of the guide along the projection is made easier. The upright face of the guide serves to direct the tip of the projection downward after it passes the rounded top a of the guide.

As shown in Fig. l, the transferrer ll is notched or grooved to receive the annular projections 7 of the head 6, and the transferrer has an extension 70, having a recessed under side to lit the top of the projection 8 during transfer, this extension being carried well out toward the extremity of the projection 8. When transfer takes place, it will be manifest that any tendency of the lillingcar rier to rock on its head portion and depress the tip will be resisted and prevented by the downward pressureof the extension it, acting upon the top of the projection 8. Should the engagement of the latter with the guide 1 exert any lifting action upon the projection, it will be counteracted by the opposite pressure of the transferrer extension 71, so that the illing-carrier will be inserted with its tip in true and accurate position.

'Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In a shuttle for automatic filling-replenishing looms, holding-jaws notched to receive the rings on the head of a filling-carrier, and an upright guide between the jaws, combined with a filling-earrier having the outer end of its head tapered, to cooperate with the guide when the shuttle is improperly positioned and cause relative longitudinal movement of the shuttle and filling-carrier to bring the notches in the jaws opposite the rings on the head of the incoming filling-carrier.

2. In a shuttle for automatic lillingreplenishing looms, holding-jaws notched to receive the rings on the head of a filling-carrier, and an upright guide between the jaws, said guide being curved rearwardly at its upper end, combined with a filling-carrier having a conical projection on its outer end, tocOOperate with the guide when the shuttle is improperly positioned and cause the same to move longitudinally to bring the notches in the jaws opposite the rings of the incoming filling-carrier.
